Calibrated Line, 20m

Product Code #1065

Marked 0 to 20m in 1m increments, this heavy, braided, stretch resistant, nylon line can be used with secchi discs to determine turbidity of water or with a 2 lb.zinc sounding weight to test overall depths of ponds, lakes, rivers, etc.

Line features a spring clip for quick attachments to plankton nets, sechhi discs, weights, etc., and is wound on a foam spool which doubles as a flotation device to prevent accidental loss of line if dropped overboard.
